  2. Pleural effusion - Wikipedia

    en.wikipedia.org/wiki/Pleural_effusion

    A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...

    en.wikipedia.org/wiki/Focused_assessment_with_s...

    eFAST (extended focused assessment with sonography for trauma) allows an emergency physician or a surgeon the ability to determine whether a patient has pneumothorax, hemothorax, pleural effusion, mass/tumor, or a lodged foreign body. The exam allows for visualization of the echogenic tissue, ribs, and lung tissue.

  5. Chylothorax - Wikipedia

    en.wikipedia.org/wiki/Chylothorax

    Since chyle is rich in triglycerides, a pleural effusion that is rich in triglycerides (>110 mg/dL) confirms the presence of a chylothorax; a pleural effusion that is low in triglyceride content (<50 mg/dL) virtually excludes the diagnosis. [11] [12] If a pleural effusion contains triglycerides between 50 and 110 mg/dL, analysis of the ...

  6. Parapneumonic effusion - Wikipedia

    en.wikipedia.org/wiki/Parapneumonic_effusion

    The criteria for a complicated parapneumonic effusion include Gram stain–positive or culture-positive pleural fluid, pleural fluid pH <7.20, and pleural fluid LDH that is greater than three times the upper limit of normal of serum LDH. [2] Diagnostic techniques available include plain film chest x-ray, computed tomography (CT), and ultrasound ...

  7. Rivalta test - Wikipedia

    en.wikipedia.org/wiki/Rivalta_test

    On the surface of this solution, 1 drop of the effusion fluid is carefully layered. If the drop disappears and the solution remains clear, the Rivalta's test is defined as negative. If the drop retains its shape, stays attached to the surface or slowly floats down to the bottom of the tube (drop- or jelly-fish-like), the Rivalta's test is ...

  8. Malignant pleural effusion - Wikipedia

    en.wikipedia.org/wiki/Malignant_pleural_effusion

    Malignant pleural effusion is a condition in which cancer causes an abnormal amount of fluid to collect between the thin layers of tissue lining the outside of the lung and the wall of the chest cavity. [1] Lung cancer and breast cancer account for about 50-65% of malignant pleural effusions.

  9. Pleural empyema - Wikipedia

    en.wikipedia.org/wiki/Pleural_empyema

    Pleural empyema is a collection of pus in the pleural cavity caused by microorganisms, usually bacteria. [1] Often it happens in the context of a pneumonia, injury, or chest surgery. [1] It is one of the various kinds of pleural effusion.
